Free CST Field Procedures & Data Collection Questions and Answers

Question 1

What is the first step before starting any field survey procedure?

Accepted Answer

Review the project scope and equipment

Answer

Before commencing any field survey, it's crucial to thoroughly understand the project's objectives, specifications, and required deliverables. This review ensures that the correct equipment is selected, calibrated, and prepared for the specific tasks. Proper planning prevents errors, saves time, and ensures the survey meets all client requirements.

Question 2

Why is it important to record environmental conditions during data collection?

Accepted Answer

They impact measurement accuracy

Answer

Environmental conditions such as temperature, atmospheric pressure, and humidity can significantly affect the accuracy of survey measurements, especially when using electronic distance measurement (EDM) instruments. Recording these conditions allows for appropriate corrections to be applied to the raw data. This ensures the final survey results are precise and reliable.

Question 3

Which tool is used to measure horizontal and vertical angles in surveying?

Accepted Answer

Total station

Answer

A total station is an electronic/optical instrument used for angle measurements (horizontal and vertical) and distance measurements. It combines a theodolite for angles with an electronic distance meter (EDM). This versatile tool is fundamental in modern surveying for precise data collection.

Question 4

What is a benchmark in surveying?

Accepted Answer

A fixed point of known elevation

Answer

A benchmark is a permanent, identifiable point on the ground or a structure whose elevation above or below a specific datum (like sea level) has been precisely determined. Surveyors use benchmarks as reference points for establishing elevations for other features. They are crucial for vertical control in surveying projects.

Question 5

Why must survey data be verified in the field?

Accepted Answer

To correct on-site errors immediately

Answer

Verifying survey data in the field allows surveyors to identify and correct any measurement errors or discrepancies while still on site. This immediate correction prevents the propagation of errors into subsequent measurements and avoids costly return trips to the field. It ensures the accuracy and reliability of the collected data.
